FLUID-DISCHARGE MEANS FOR BOTTLES.

Application filed February 21, 1921. Serial No. 446,619.

' T aZZ whom it may concern:

Be it known that I, BENJAMIN E. ROBIN soN, a citizen of the United States, residing at Sallyards, in the county of Greenwood and- State of Kansas, have invented certain new and useful Improvements in Fluid-Dis charge Means for Bottles, of which the following is a specification.

This invention relates to fluid discharge means for bottles.

The object of the invention is to provide a simple and efficient bottle closure equipped with means to produce a non-pulsating outflow eliminating the gurgling and bubbling ordinarily incident to the emptying of such.

receptacles.

Another object is to provide a bottle closure equipped with means for admitting a1r to the bottle during the escape of 1ts contents thereby preventing bubbling and the consequent splattering.

With these and other objects in View, the invention consists in certain novel features of construction as hereinafter shown and described and specifically pointed out in the claims.

In the accompanying drawing:

Figure 1 represents a longitudinal section of the upper end of a bottle with this improvement shown applied and in side elevation.

2 is a longitudinal section of the device constituting this invention with a portion of the air tube broken off for convenience in illustration, and,

Fig. 3 is a transverse section taken on the line 3-3 of Fig. 2.

It is well known that in pouring liquid contents from a small mouthed receptacle such as a bottle that gurgling, bubbling and splashing of the outcoming contents occurs owing to the entrance of air through the outgoing liquid. It is to overcome this objectionable feature that this device is intended and it is here shown applied to a bot. tle B having the ordinary reduced mouth M.

The device constituting this invention comprises a hollow tubular shell 1 constructed of any suitable metal, preferably of alumi-' num or nickleiand is preferably made tapering throughout with its smaller inner end 2 offset inwardly and provided at its base with a shoulder 3 which forms an abutment for a rubber gasket 5 which encircles the reduced inner end of the shell and preferably is of a width corresponding to the length of this end as is shown clearly in Fig. 2. The outer end or mouth of the shell '1 has a laterally extending flange or bead 4 which is designed to provide a suitable finish and to assist in pouring.

The gasket 5 is of slightly greater thickness than the width of the shoulder 3 so that when applied the perimeter thereof will project slightly beyond that of the main or body portion of the shell 1 as is shown clear ly in Fig, 2 to adapt the closure to fit snugly 4 within the mouth M of the bottle to prevent leakage past the closure, the gasket carried end of said shell conforming in shapeand size to the cork used to seal the bottle and which is designed to replace said cork for. pouring purposes, the cork fittingin the outer portion of the shell, as shown in dotted I preferably cast integral therewith as is shown clearly in Fig.3. This tube 6 tapers from its outer toward its inner or attached end providing a funnel-like air inlet opening midway the length of the shell 1 or at a point flush with the inner face of the shoulder 3 and which is closed ordinarily by a stopper S of cork or other suitable material, the inner end of the cork resting on the shoulder 3. The tube 6 is of a length sufficient to position its enlarged discharge end 7 adjacent one side wall of the bottle B in connection with which it is to be used as shown in Fig. 1 which constitutes the air space of the bottle when it is turned sideivise in the position for pouring as shown in ig. 1. i

In the use of this device which is primarily intended as a substitute for the sealing stopper, the bottle B which may be a carboy, having been delivered filled with liquid the sealing stopper is removed and the pouring shell 1 is inserted in the mouth thereof fluidtight therein with the air inlet pipe 6 arranged as shown, when the bottle is turned down for pouring. The cork S is placed in the mouth ofthe shell 1 after the desired quantity of liquid has been removed to protect that remaining.

Then it is desired to remove the contents of the bottle the stopper S is removed and the bottleturned on one side with the air inlet tube 6' disposed upwardly as shown in i Fig. 1, the air entering the bottle through said tube to permit the contents of the-bot-' tie to flow out through thezshell lxwithout bubbling or gurgling and the incident splashing ordinarily occurring when'ipour- ='it"*'fac-ilitates "the "'no n splashin'g" discharge thereof.
